A woman was arrested by Pasadena police this week for allegedly supplying her minor child with synthetic marijuana, according to Harris County court documents.

Christine Reyna, 33, was charged with endangering a child on Tuesday afternoon.

Vance Mitchell, spokesman with the Pasadena Police Department, said two Pasadena police officers on bicycles were riding through an apartment complex off Burke when they saw a woman and a teen boy together.

According to police, when the boy saw them he quickly dropped something he had been smoking. Police then approached the pair to investigate, and found out that Reyna had purchased a packet of synthetic marijuana for her teen son to smoke.

The woman was arrested by police and her son was released into the custody of family members. He did not require medical assistance.

Mitchell said synthetic weed is especially troublesome for Pasadena narcotics officers. While it is legal, it can be very dangerous to use. It is made by spraying natural herbs with synthetic chemicals. Several states in the U.S. have passed laws banning it.

"If the law shuts down on one brand of it, the name or the chemicals change and they just begin selling it again," he says. The fake pot is usually sold at smoke shops, convenience stores and gas stations. Mitchell says that to his knowledge Pasadena's problems with it are no different than any other city's.

A Houston Chronicle story late last year reported on the DEA's seizure of the synthetic weed and the dangerous side effects that can come from smoking it.

Reyna is currently out on $2,000 bond. Her next Harris County court appearance is March 18.
